Abstract

Provided is a decontamination apparatus for rendering an object pathogen reduced. The decontamination apparatus includes a frame to be positioned in suitable proximity to the object to enable the decontamination apparatus to perform a decontamination process that achieves at least a predetermined minimum level of pathogen reduction on the computer peripheral. A light source coupled to the frame to be transported along a decontamination path emits ultraviolet light suitable to deactivate at least a portion of a pathogen population on the computer peripheral. A shield interferes with transmission of the ultraviolet light in directions generally away from the computer peripheral, and a controller operates the light source and transports the light source along the decontamination path during the decontamination process.

Claims (41)

1. A decontamination apparatus for rendering an object pathogen reduced, the decontamination apparatus comprising:

a frame to be positioned in suitable proximity to the object to enable the decontamination apparatus to perform a decontamination process that achieves at least a predetermined minimum level of pathogen reduction on the object, wherein the frame comprises a track region along which the coupler travels to transport the light source along the decontamination path;

a light source that emits ultraviolet light suitable to deactivate at least a portion of a pathogen population on the object;

a coupler that receives the light source and is adjustable relative to the frame to allow the light source to be transported along a decontamination path during the decontamination process;

a shield that interferes with transmission of the ultraviolet light in directions generally away from the object during the decontamination process;

a controller that controls operation of the light source and transportation of the light source along the decontamination path during the decontamination process;

a motor that is controlled by the controller; and

a drivetrain that transmits a force generated by the motor to the coupler to transport the light source along the decontamination path, wherein the drivetrain is coupled to the frame and comprises a continuous loop of material that extends about at least a drive hub that is rotatable by the motor.

2. The decontamination apparatus of claim 1 , wherein the drivetrain comprises an arm with a proximate end that cooperates with a drive shaft and a distal end that supports the light source, and rotation of the drive shaft results in rotation of the arm to transport the light source along the decontamination path.

3. The decontamination apparatus of claim 1 , wherein the light source predominantly emits ultraviolet light having a wavelength within a range from approximately 10 nm to approximately 400 nm.

4. The decontamination apparatus of claim 1 , wherein the shield comprises an inward-facing surface opposing the light source with an anti-reflective material that interferes with reflection of the ultraviolet light in the directions generally away from the object in a second direction generally towards the object.

5. The decontamination apparatus of claim 4 , wherein the anti-reflective material provided to the inward-facing surface is a matte coating.

6. The decontamination apparatus of claim 1 , wherein the light source and shield maintain a constant orientation relative to the object over an entire range of travel during the decontamination process.

7. The decontamination apparatus of claim 1 , wherein the coupler comprises an arm that transports the light source along an arcuate path over the object.

8. The decontamination apparatus of claim 1 , wherein the frame comprises a pair of rails separated from each other by an adjustable distance, and at least one strap that extends between the rails and about the object to secure the frame on the object between the rails.

9. The decontamination apparatus of claim 1 further comprising a sensor in communication with the controller, wherein the sensor is operable to sense a person within a defined distance from the object and communicate with the controller to cause deactivation of the light source in response to sensing the person within the defined distance.

10. The decontamination apparatus of claim 1 , wherein the controller is configured to cause the light source to be transported along the decontamination path at a plurality of different velocities.

11. The decontamination apparatus of claim 10 , wherein the plurality of different velocities are established by the controller in response to user input.

12. The decontamination apparatus of claim 1 further comprising a guard that interferes with transmission of the ultraviolet light from a portion of the light source, wherein the guard is supported with the light source arranged between a portion of the shield and a baffle.
